Hello, We are developing the following datastore for a big application.
One table with 10.000.000 records. The application has at any given time 40.000 active users. These users make frequently adjustments to these records. In rare cases, more than one user writes to a single record. What happens if a specific user does four requests in a row to adjust a single record. For example: Entity Email with property content; Request 1: get Email, add 'hello' to content, put Email. Request 2: get Email, add ',how' to content, put Email. Request 3: get Email, add ' are y' to content, put Email. Request 4: get Email, add ' doing' to content, put Email. How can I ensure that the content property has the value 'hello, how are y doing' after the fourth request? The entity group Email, has no parent. Is this scenario strongly consistent? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
